Bine, a citizen of the United States, residing at Troy, in the county ot RenSSe-laer, State of New Xorlr, have 1nmitted into said oven for cooking or other purposes, when the coal stovey is not in service, or cutoff therefrom, in which latter case, the oven may receive its heat from the coal stove, the latter thenbeing serviceable as usual, or -iu other words, the oven of a coal .stove is utilized to be heated b v a. gas stove. i

The invention is satisfactorily illustrated in the accompanying drawing, but the important instrumentalities thereoil .may be varied, as long as they` are included in the scope of the claims.

GGIVBNED CL AND GAS STOVE.

Specification of Letters Patent.

Patented Nov. '7, 1916.,

Similar numerals of reference 'indicate corresponding parts in the figures.

Referring to the d rawiiigs, `1 designates portions of a coal store embodying the oven 2, the ash pit 3. and the flue i for the products of combustion.

ln the portion of the flue 4 belowthe bottom wall 5 is the chamber or compartment (S, which is not in communication with said fine, it containing the gas burner 7 with which is connected the gas-supply'pipe '8.

In the upper face of the bottom 5 of the oven is an opening 9, the wall of which is `depressed forming the seat lO for the verticallyY movable valve 11 which consists of a plate which whenraised admits the'chain- ,ber 6 to be in communication with the oven 2, through said opening 9, and which when lowered closes said opening' and so shuts off said communication, it being'evident that when the burner 7 is ignited, and the valve is raised or opened, the heat of'the former will enter the oven, and so be availed-of, as shown in Fig. 5 to heat the oven, in which case the coal stove as such is not in service. When however, said stove is required for service, the burner is not lighted, and the valve lowered or closed as inFigs. 2 andB, the oven receiving its heat from the coal stove as usual.

lVithin the 'oren is the tra)Y or shelf lffor Y supporting utensils` i'or cooking` etc., and Figure 1 represents a top or plan. View y trally from said valve 11 and entering the chamber is the hanger 15 which is composed of a bar .adapted to raise and lower said nlve, it beine,` pivotally connected near its lower end with the swinging;- link 16' which is pirotall)v mounted on the ear 17 on the inner side of the wall of the chamber 6, and? adapted to guide saidA banner, vand consequenthY theralve 11 in its opening and On the side of tliehanger the projection or lug 18 which is sented on the inclined plane 19 which passes freely through the bifurcation 20 o'n the lower end of the hanger 15 as a guide for the latter and is 5 connected with the sliding valve21, which occupies a position in the air chamber 22 at the base of the gas burner chamber 6, the sides of said chamber having therein air inlet ports 23, said valve 21 being composed l in the rent case of a four sided frame which 1s adapted to open :and close said ports to admit air to the burner, or cut it off therefrom, as required. YVhile said inclined plane rides on said lug the latter, when the l5 hanger is raised, is adapted to abut vthe burner 7 and so limit the ascent of the valve. The side 2l of the valve 21 has its seat on the flange 2Q on the wall of the air cham- A ber 22, so that when saidvalve is drawn out, it is removed from said flange, allowing air to enter the burner at saidv side of the valve, but when said valve is pushed in, it is closed .against said valve, the effect of which is evident.

Connected with the exterior of the side 24 of the valve is the bar or rod 26 which passes under the'flue 4 and below the door 27 of the oven 2 of the stove, where it is provided with the grip or handle whereby the air supply and regulating l valve 2] may be moved in opposite directions, it being evident that when said valve is drawn out, the inclined plane 19 rides on the lug 1S and moves the same, and consequently the 35 hanger 15 upward, whereby the valve l1 is raised and consequently opened, and when said valve is pushed in, the corresponding movement of the inclined plane permits said valve to lower and so close on its seat.

Secured to the grip or handle 2S and extending` laterally therefrom is the ai-in 2S), whose free end is adjacent to the handle 30 of the cock 31 ot' thc gas supply pipe 8, so

that when the bar or rod 26 ispushed in to close the valve l1 and the gas is shut-off, said free end of the arm is at the side of said handle in the closed condition of said cock 31, thus preventingr the handle of the latter from being operated and unnecessarily or improperly turning on the gas, as plainly Shown in Fig. l, but.' when the bar or rod is drawn out, and lhc valve 11 is opened,fas shown dotted in Fig. 4, the arm 2!) is removed, the said handle 30 allowing the latter to be operated to turn on the gas.

The side walls 32 of the air chamber 22 are higher at one end than at the other, as shown 4in Figs. 2 and 8, owing to the different altitudes of the bottom of the flue 4 to which said walls are bolted, and one of the walls 33 has thereon a depression 34, as a seat for the portion of the gas supply pipe which enters the chamber (i and is connected with the burner 7 therein.

.movable valve, the bottom of said'oven 'supporting hanger for clined member in said compartment adapted It is evident that when the valve 11 is in closed position, the .gas heating attachment is cut olf from the oven, and vice versa, and nothing in the oven can enter the chamber of said attachment, and :the coal stove as such has its usual functions.
